PS6000 Hardware Maintenance Maintaining Control Modules
3–5
To display the firmware version running on an array, examine the GUI Member
Controllers window or use the CLI
member select show controllers
command. If the firmware on a micro SD card does not match the firmware
running on an array, do not install it. Instead, contact your array support provider.
Network Configuration Recommendations
Dell recommends that you follow the guidelines in the table shown next. In
addition, all the usual rules for proper network configuration apply to group
members. General network configuration is beyond the scope of this manual.
Table 3-3: Network Recommendations
Recommendation Description
Switched Gigabit
Ethernet network
Connect arrays and hosts to a switched network and make sure
that all network connections between hosts and arrays are
Gigabit Ethernet. Although an array can operate at 10 or 100
Mbits, performance will be slower than when using a Gigabit
Ethernet switch.
Multiple network
connections
For increased bandwidth and availability, connect all the
network interfaces on both control modules to multiple network
switches.
The switches must be connected using interswitch links. The
links must have sufficient bandwidth to handle the iSCSI
traffic.
After connecting the network interfaces, use the Group
Manager GUI or CLI to assign an IP address and netmask to
each interface.
Access to the group IP
address
In a multi-subnet group, each configured network interface
should have access to the subnet on which the group IP address
resides.
Redundant network
paths
Using a multipathing solution helps to make sure that no single
point of failure exists between computers and arrays.
For replication, a
reliable, adequately
sized network link
For effective and predictable replication, make sure that the
network link between the primary and secondary groups is
reliable and provides sufficient bandwidth for copying data.
